X5 SMD Series D110 LED Downlight 10-15W

What is the X5 SMD Series D110 LED Downlight and where is it specified?

At XHLWX (led-project-light.com), a Custom Indoor LED Lighting Manufacturer based in China, we design and produce specification-grade luminaires for export to European, North American, and Middle Eastern markets. The X5 SMD Series D110 is a cornerstone of our general lighting portfolio, offering a versatile and efficient solution for commercial, hospitality, and high-end residential applications. This recessed downlight, available in 10W and 15W configurations, is engineered for projects requiring broad, uniform illumination from a compact and discreet source. With a standard Ø110mm trim and requiring just a Ø90mm cutout, it's an easy-to-specify fixture for both new construction and retrofits. Its defining feature is a high-transmission PC diffuser that delivers a wide 120° beam angle, ideal for creating ambient light layers and reducing the number of fixtures required to light a space. Coupled with high-efficacy performance up to 130 lm/W and exceptional color rendering options up to CRI 98+, the X5 D110 is a dependable workhorse for lighting specifiers and electrical contractors.

Which spaces is it designed for?

As a versatile general lighting tool, the X5 D110 excels in a variety of commercial environments where comfortable, widespread illumination is the primary goal. Its high customisability allows specifiers in the EU and US to adapt it perfectly to project needs.

How can this downlight be used for general lighting in offices and schools?

In corporate offices and educational facilities, the X5 D110 is ideal for circulation spaces like corridors, lobbies, and break rooms. The 120° beam allows for wider fixture spacing while still achieving uniform illuminance levels of 150-200 lux. For these applications, a 15W version in 4000K with CRI>80 offers a balance of visual comfort and high energy efficiency (over 120 lm/W), helping to meet stringent building energy codes. The DALI-2 dimmable driver option allows for integration into building-wide lighting control systems for daylight harvesting or scene setting.

Is the X5 D110 suitable for hotel guest rooms and back-of-house areas?

The X5 D110 is an excellent choice for hospitality projects. In guest rooms, the 10W version specified at a warm 2700K or 3000K CCT creates a welcoming ambiance. Paired with a TRIAC-dimmable driver, it provides simple, cost-effective dimming control for guests. For back-of-house corridors, staff areas, and storage rooms, the 15W, 4000K, CRI>80 variant provides bright, functional light that enhances safety and productivity. The robust die-cast aluminum construction ensures durability in high-traffic service areas.

What are the best applications in a retail environment?

While not an accent light, the X5 D110 serves a critical role in layered retail lighting schemes. It provides the base ambient light in boutiques, fitting rooms, and common areas. By specifying a high-CRI version (CRI>95, Ra>98), retailers can ensure merchandise colors are rendered accurately and vibrantly. The soft, diffuse light from the 120° optic minimizes harsh shadows, creating a more pleasant shopping experience. It's also a highly effective solution for stock rooms where clear visibility and color identification are important.

Installation, control and compliance (DALI-2 / Casambi / 0-10V, CE / RoHS / ErP)

Engineered for contractor efficiency, the X5 D110 installs quickly into a standard Ø90mm (3.5 inch) ceiling cutout using two robust spring-loaded clips. The low-profile housing (53mm height) is suitable for plenums with limited depth. The luminaire is powered by a remote, constant-current driver connected via a simple plug-and-play connector.

Control is a key strength. We offer drivers for any specification:

• DALI-2: For addressable digital control in smart buildings.
• 0-10V / 1-10V: For simple and reliable analog dimming.
• TRIAC (Phase-cut): For cost-effective residential and hospitality retrofits.
• Wireless: Casambi (BLE) and ZigBee options for app-based control and flexible installations without new control wiring.

Full compliance with European standards is assured. The product is CE marked, meeting Low Voltage (LVD) and Electromagnetic Compatibility (EMC) directives, and is fully RoHS compliant. ErP data is available to support energy performance calculations.

Customisation, MOQ and lead time

As a lighting manufacturer, we specialize in tailoring products to meet your exact project requirements. Beyond the standard options, the X5 D110 can be customized in several ways:

• Color Output: Tunable White (TW), Dim-to-Warm (DTW), RGB, and RGBW versions are available for dynamic lighting applications.
• Driver Specification: We can source and integrate a specific driver part number if required for your project.
• Finish: Custom RAL powder coat finishes can be applied for large projects.

The standard Minimum Order Quantity (MOQ) for this series is 100 units. For smaller quantities or sample requests, please contact our sales team. Our typical production lead time is 20-25 working days from the confirmation of technical specifications and payment.

Frequently Asked Questions

Q: Do you provide IES files for the X5 SMD D110 for lighting design software?

A: Yes, we provide complete photometric data for all variants. IES and LDT files are available for download upon request, allowing for precise simulation in software like DIALux EVO or AGi32. Our files are based on goniophotometer testing and include data for all CCT and CRI options. The 15W model, for example, can produce over 1800 lumens.

Q: Can this downlight be specified with a specific brand of DALI driver?

A: Absolutely. While we standardize on high-quality drivers, we can integrate specific models from Tridonic, Osram, Mean Well, or others to match project requirements. Our DALI-2 compatible drivers ensure seamless integration into building management systems. Just provide the driver part number, and we will confirm compatibility. Lead times for non-standard drivers may vary by 5-7 days.

Q: What are the TM-30 values for the high-CRI versions?

A: For our CRI>95 variants, you can expect excellent colour rendition metrics. A typical 3000K CRI95+ version will have a TM-30-18 fidelity index (Rf) of around 92 and a gamut index (Rg) of 99. These values ensure that colours are rendered both accurately and vividly, making them ideal for retail or gallery applications. We provide specific TM-30 reports with our photometric data packs.

Q: What does the 5-year warranty cover?

A: The 5-year warranty covers the complete luminaire, including the LED module and the external driver. It guarantees against defects in materials and workmanship under normal use. We warrant that the luminous flux will be maintained at >80% (L80B10) of its initial value for at least 50,000 hours of operation. In case of a verified failure, we will provide a replacement.
